ZURICH, Feb 9 (Reuters) - Clariant has halted plans to issue an update of its strategy after an activist investor sold its 25 percent stake in the Swiss speciality chemicals maker to Saudi Basic Industries Corp (SABIC) last month.

Clariant had said in November it would issue the update after U.S.-based investment vehicle White Tale demanded three Clariant board seats and called for an independent review of the Swiss firm by an investment bank.

The update, which Clariant intended to deliver in early 2018, was to cover merger and acquisition (M&A) activities, short-term portfolio management options, returns to shareholders and cost structures.

But Chief Executive Hariolf Kottmann’s plan is now on hold until he learns more during upcoming meetings with SABIC, now the largest Clariant shareholder.

“We have a completely new situation,” a Clariant spokesman said on Friday. “The strategic update started immediately, but now it does not make sense to proceed with something that was started under completely different circumstances.”

Clariant executives have had informal talks with SABIC managers but have yet to have a formal meeting on strategy.
